Tom drew a chalk circle of about three feet diameter round the spot, and then called to me to come and join him. "We've managed this business together, Jack," he said, "and we'll find what we are to find, together." The circle he had drawn embraced a part of the rock smoother than the rest, save that about the centre there were a few rough protuberances or knobs. One of these Tom pointed to with a cry of delight. It was a roughish, brownish mass about the size of a man's closed fist, and looking like a bit of dirty glass let into the wall of the cliff. "That's it!" he cried--"that's it!"
"That's what?"
"Why, man, /a diamond/, and such a one as there isn't a monarch in Europe but would envy Tom Donahue the possession of. Up with your crowbar, and we'll soon exorcise the demon of Sasassa Valley!"
I was so astounded that for a moment I stood speechless with surprise, gazing at the treasure which had so unexpectedly fallen into our hands.
"Here, hand me the crowbar," said Tom. "Now, by using this little round knob which projects from the cliff here as a fulcrum, we may be able to lever it off. Yes; there it goes. I never thought it could have come so easily. Now, Jack, the sooner we get back to our hut and then down to Cape Town, the better."
We wrapped up our treasure, and made our way across the hills toward home. On the way, Tom told me how, while a law student in the Middle Temple, he had come upon a dusty pamphlet in the library, by one Jans van Hounym, which told of an experience very similar to ours, which had befallen that worthy Dutchman in the latter part of the seventeenth century, and which resulted in the discovery of a luminous diamond. This tale it was which had come into Tom's head as he listened to honest Dick Wharton's ghost-story, while the means which he had adopted to verify his supposition sprang from his own fertile Irish brain.
"We'll take it down to Cape Town," continued Tom, "and if we can't dispose of it with advantage there, it will be worth our while to ship for London with it. Let us go along to Madison's first, though; he knows something of these things, and can perhaps give us some idea of what we may consider a fair price for our treasure."
We turned off from the track accordingly, before reaching our hut, and kept along the narrow path leading to Madison's farm. He was at lunch when we entered; and in a minute we were seated at each side of him, enjoying South African hospitality.
"Well," he said, after the servants were gone, "what's in the wind now? I see you have something to say to me. What is it?"
Tom produced his packet, and solemnly untied the handkerchiefs which enveloped it. "There!" he said, putting his crystal on the table; "what would you say was a fair price for that?"
Madison took it up and examined it critically. "Well," he said, laying it down again, "in its crude state about twelve shillings per ton."
"Twelve shillings!" cried Tom, starting to his feet. "Don't you see what it is?"
"Rock-salt!"
"Rock-salt be d--d! a diamond."
"Taste it!" said Madison.
Tom put it to his lips, dashed it down with a dreadful exclamation, and rushed out of the room.
I felt sad and disappointed enough myself; but presently, remembering what Tom had said about the pistol, I, too left the house, and made for the hut, leaving Madison open-mouthed with astonishment. When I got in, I found Tom lying in his bunk with his face to the wall, too dispirited apparently to answer my consolations. Anathematising Dick and Madison, the Sasassa demon, and everything else, I strolled out of the hut, and refreshed myself with a pipe after our wearisome adventure. I was about fifty yards from the hut, when I heard issuing from it the sound which of all others I least expected to hear. Had it been a groan or an oath, I should have taken it as a matter of course; but the sound which caused me to stop and take the pipe out of my mouth was a hearty roar of laughter! Next moment Tom himself emerged from the door, his whole face radiant with delight. "Game for another ten-mile walk, old fellow?"
"What! for another lump of rock-salt, at twelve shillings a ton?"
" 'No more of that, Hal, an you love me,' " grinned Tom.
